Zip code 95460 has one elementary-level school, Mendocino K-8, serving grades K–8 and enrolling 241 students, so there is no local school-to-school comparison.

The clearest overall finding is that science was the school’s strongest state-relative subject, 14 percentage points above California.
There is no separate top- or bottom-ranked school in this ZIP-code list: Mendocino K-8 is the only school, and its results vary considerably by grade. Its all-grades mathematics proficiency was 6 points above the state rate, and science was 14 points above; ELA was 1 point below. Grade-level results show why those averages do not describe every student’s experience: math proficiency ranged from 16% in grade 5 to 65% in grade 8. Grade 5 was 21 points below California, while grade 8 was 28 points above. ELA also ranged widely, from 29% in grade 6 to 71% in grade 8.
Results moved in different directions over time: ELA fell 7 percentage points, from 55% in 2024–2025 to 48% in 2025–2026, while math rose 2 points and science rose 8. SchoolDigger’s reported school percentile also declined, from 68 in 2023–2024 to 60 and then 43 in 2025–2026; separately, SchoolDigger lists Mendocino Unified at rank 245 of 968, the 75th percentile, with four stars.
